In embodiments of access point assisted roaming, a mobile device, such as a mobile phone, tablet computer, or other portable device is implemented for wireless connection with access points, such as Wi-Fi access points. An access point controller can receive a request for a neighbor report from the mobile device, and also obtain a travel direction of the mobile device. The access point controller is implemented to determine access points that are each configured for a wireless connection with a communication system of the mobile device, where a wireless connection with an access point is based in part on a detected signal strength of an access point. The access point controller can then generate the neighbor report that lists one or more of the access points in order of connection likelihood and based on the travel direction of the mobile device.

Access point assisted roaming

A wireless computing device operating as a controller of a peer-to-peer group configured to generate unique master keys for each device joining the group. The wireless computing device may use the unique master keys to selectively remove remote devices from the group such that the remote device cannot later rejoin the group. Other remote devices, each possessing a master key that remains valid, can disconnect from the group and later reconnect to the group without express user action. To support such behavior, the wireless device may provide a user interface through which a user may manage connected remote devices by providing commands to selectively disconnect or remove remote devices from the group.

Secure protocol for peer-to-peer network

Methods and apparatus are disclosed for device discovery, pairing, and transmission of audio and video media, using preference data shared between a media sender/source node and a media receiver/sink node. In some examples of the disclosed technology, a sink node sends, via a peer-to-peer wireless communication path, a discovery message to a source node comprising a preference indication including an indication of a first one of two communication paths to use for the establishing a connection. The sink node receives a request to establish a connection between the sink node and the source node based on the indicated preference. Based on the received request, the sink node establishes a connection between the sink node and the source node. A selected communication path (e.g., peer-to-peer wireless or wireless infrastructure) can be indicated as preferred, along with additional parameters for the media connection.

Dynamic identification of network connection preferences

A computing device for provisioning a wireless device for connection to a wireless network via a legacy access point. The wireless device supports a wireless protected setup protocol for obtaining the network profile of the network. A user requests the computing device discover wireless devices for provisioning. In response to the user input, the computing device is configured as a soft access point and broadcasts a beacon signal indicating that the access point supports a wireless protected setup protocol, such as Wi-Fi Protected Setup. A request for provisioning is then received by the computing device from the wireless device. A network profile is transmitted from the computing device to the wireless device in accordance with the wireless protected setup protocol. The wireless device may use the profile to connect to the network via the legacy access point using the network profile.

Wireless provisioning a device for a network using a soft access point

In one example, a Wi-Fi client device may streamline a dynamic frequency selection check using a channel baseline measurement. The Wi-Fi client device may select a sampling size for a dynamic frequency selection check based on a channel baseline measurement for a dynamic frequency selection Wi-Fi channel. The Wi-Fi client device may execute the dynamic frequency selection check using the sampling size on the dynamic frequency selection Wi-Fi channel. The Wi-Fi client device may establish a Wi-Fi Direct connection based on the dynamic frequency selection check.

Client-side dynamic frequency selection check

A dock for interacting with a computing device. The computing device configures itself for operations based on its context, which may be determined form the dock by reading a value from a tag on the dock. The computing device may use low power transmissions such that receiving a value from the tag provides an indication of proximity to the dock. The value read provides an indication of a desired operation, and, in response to reading a value of the tag, the computing device may launch an application, pair with devices in the vicinity of the dock, or take other actions that configure the computing device. A universal dock, usable with computing devices of a plurality of form factors, may be implemented by providing an array of tags and, in some cases, a non-contact power supply.

Universal dock for context sensitive computing device

Technology for allocating network adapter resources such as air interface time and queue space amongst multiple virtual network stations or other virtual adapters is disclosed. As one example, the resource allocation may be based on analysis of the relative latency, jitter, or bandwidth considerations for applications communicating via each of the multiple virtual adapters. The resource allocation may also be based on how efficiently each of the virtual adapters utilized previously allocated resources.

Allocation of shared resources for virtualized networking

An access point device is configured to improve usability of tethering, while improving battery life and managing data usage among and by the tethered devices. Both access point devices and client devices can remain in a low power state without a high power radio being powered until a shared network connection is to be used. To establish a connection to a network for the client device, the client device communicates with the access point device over a lower power communication device, such as a low power radio. The access point device activates its higher power radio. The two devices then connect over the high power radio, allowing the client device to then to use the access point device as a router to connect to a computer network.

Efficient automatic sharing of network access among devices

A mechanism for a wireless device to obtain access to network connectivity through a WAN-enabled device. The wireless device may use peer-to-peer communication to request the WAN-enabled device enter a mode in which it serves as an access point to its WAN. The wireless device may then associate with the WAN-enabled device in its role as an access point to access connectivity services. Such a capability may be used, for example, to allow a wireless computing device to gain access to the Internet through a smartphone or other device that has Internet access, and can also be configured to communicate in accordance with the Wi-Fi and Wi-Fi Direct standards.
